- An oil storage tank contains oil with specific gravity of 0.88 and depth of 20 meters. What is the hydrostatic pressure at the bottom of the tank in kg/cm2?arrow_forwardFigure 2.23 shows a U-tube manometer used to measure the small pressuredifference of the two water pipes. The top of the tube is filled with a liquidwhich is lighter than water and immiscible with water. It is known that the relative densities of the liquid in tube A and B ared1= d3 = 1, and the relative density of the liquid in the U-tubemanometer is d2 = 0:95. If h1 = h2 = 0.3 m and h3 = 1 m, try to determine the pressure difference pB - pA.arrow_forwarda drum has gasoline s.g=0.9, with oil s.g=0.8 and sea water s.g=1.03. the depth of the liquid is 0.8m, 0.5m, and 1.0 for gasoline, oil and sea water.1. find absolute pressure at depth 1.2m 2.find the depth at 1.8m 3. find the force F at depth 2.1m when diameter of drum is 0.5marrow_forward
- Due to unavailability of mercury, a barometer was constructed using water in the closed column with a certain amount of oil on top to prevent the boiling of the water. For standard atmospheric pressure, what height of oil will be required and how high will the column of water be if the minimum pressure at the water-oil interface is to be 1 psia? Water density is 62.4 lb/ft³; specific gravity of oil is 0.8.arrow_forwardIf you have a seawater aquarium, you have probably used a small cylindrical glass tube with a lead-weight at its bottom to measure the salinity of the water by simply watching how deep the tube sinks. Such a device that floats in a vertical position and is used to measure the specific gravity of a liquid is called a hydrometer . The top part of the hydrometer extends above the liquid surface, and the divisions on it allow one to read the specific gravity directly. The hydrometer is calibrated such that in pure water it reads exactly 1.0 at the air–water interface. (a) Obtain a relation for the specific gravity of a liquid as a function of distance Δz from the mark corresponding to pure water and (b) determine the mass of lead that must be poured into a 1-cm-diameter, 20-cm-long hydrometer if it is to float halfway (the 10-cm mark) in pure water.arrow_forward6. You are a researcher at a company that makes pressure cookers, and you are in charge of designing the plug weights for pressure cookers. If the operating pressure of the stopper weight of the pressure cooker is 100kPa as the gauge pressure and the cross-sectional area of the steam outlet is 5mm', what should the mass of the stopper weight be? In addition, Mexico City is said to be about 75 to 80% of the atmospheric pressure at sea level at 2200m above sea level. If a pressure cooker is exported to Mexico City, what should be the mass of the stopper? Assume that the standard atmospheric pressure in Korea is 80% of the standard atmospheric pressure in Mexico City. (However, the acceleration due to gravity is 9.81m/s")arrow_forward
- The center of pressure is equal to the total pressure force in case of a vertical plane surface submerged in liquid. Select one: Truearrow_forwardWhat would be the SG of a gas with a specific weight of 0.127 lb/ft3, if the density of air under the same conditions is 0.0037 slugs/ft3?arrow_forwardKindly supply all questions neatly thank you A closed tank whose bottom is 18 inches in diameter is filled with three liquids: 12 inches of carbon tetrachloride (SG=1.59), 4 inches of water and 2 inches of syrup (SG=1.31). The air chamber in the tank is pressurized at 9 psi. Illustrate the problem before solving a. Determine the pressure at the interface of water and syrup. b. Determine the difference in pressure between the interface of water and syrup and the interface of carbon tetrachloride and syrup c. Compute the hydrostatic pressure (in psi) acting at the bottom of the tank d. Apply the PANEL EQUATIONS to determine the magnitude, direction and location of the total hydrostatic force acting at the bottom of the tank. .arrow_forward
- What height of mercury column is equivalent to 1000 kPa? The density of mercury is 14000 kg/m3.arrow_forward4. A U-tube manometer filled with mercury is attached to a gas tank. The level of mercury on the open end of the manometer is 40 cm higher than the level at the end attached to the tank. What is the gage pressure of the gas inside the tank? 5. For item 4, what is the absolute pressure of the gas inside the tank? 6. For item 4, if the level of mercury on the open end is 60 cm lower than the level at the end attached to the tank, what is the absolute pressure of the gas?arrow_forward1. A vertical semi-circular area of radius r is submerged in a liquid with its diameter in the liquid surface. How far is the center of pressure from the liquid surface? 2. An open vat holding oil (s=0.80) is 8 m long and 4 m deep and has a trapezoidal cross-section 3 m wide at the bottom and 5 m wide at the top. Determine the following: (a) the weight of oil, (b) the force on the bottom of the vat, and (c) the force on the trapezoidal end panel.arrow_forward
